The Cortex Self-Tapping 4.5mm Screws with Hexagonal Socket (20 to 60mm) are robust orthopedic implants used for internal fixation of fractures in long bones. These screws are designed for use with dynamic compression plates (DCP), reconstruction plates, and other AO-compatible systems to provide strong and reliable cortical bone fixation.
The self-tapping design allows the screw to cut its own thread during insertion, eliminating the need for pre-tapping in most cases. This reduces surgical time, improves efficiency, and ensures smooth and accurate insertion into cortical bone.
The hexagonal socket head provides secure engagement with the screwdriver, ensuring excellent torque control and reducing the risk of stripping during insertion. This allows precise placement and stable fixation during orthopedic procedures.
The 4.5mm diameter screws are commonly used in fixation of large long bones such as femur, tibia, and humerus, especially in adult orthopedic trauma cases requiring high load-bearing strength.
The length range of 20mm to 60mm provides flexibility for different anatomical requirements and fracture patterns, allowing surgeons to select the appropriate screw size for optimal fixation.
Manufactured from premium surgical-grade stainless steel or titanium (depending on configuration), the screws offer excellent strength, corrosion resistance, and long-term durability under physiological load.
These screws are fully compatible with standard AO orthopedic systems and are widely used in both human and veterinary orthopedic surgeries.
The implants are fully sterilizable and supplied in professional surgical packaging for safe handling and efficient surgical workflow.
